I think this is a new genre that they're all sort of working their way through it and haven't got all the kinks worked out yet but it's a genre that works for me.

This is a must-see and one of the best documentaries - and films - of this year.

Great story, amazing characters, superb action, enthralling cinematography. Yes, this is something I am glad I spent money on.
